Collective responses of animals are generally controlled by complex biological mechanisms and in Caenorhabditis eleganscollective dynamics are purely controlled by physical parameters such as oxygen penetration and bacterial diffusion.
The ability of Vaccinia virus to induce actin polymerisation depends on the relative binding position of adaptors within the signalling network activating the Arp2/3 complex.

The concentration of motile bacteria, expressing a light-driven proton pump, can be precisely controlled in space and time by spatially modulating their swimming speeds with a structured light pattern.

Time-resolved phosphoproteomics and thermal proteome profiling reveal the Ca2+-responsive proteome of the model apicomplexan Taxoplasma gondii, identifying PP1 as a Ca2+-responsive enzyme that regulates Ca2+ uptake to promote parasite motility.
NDR kinase Orb6 prevents RNP granule assembly and translational repression by promoting Sts5 association with 14-3-3 protein Rad24 to spatially control polarized cell growth.

Efficient dedifferentiation is characterized by robustness to mutation, flexibility in ordering of cellular events and reversal of developmental changes along a single gene expression trajectory.

An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.

Computational and experimental studies show that different migration modes of eukaryotic cells are the result of the interplay between signaling waves and cell mechanics.
